    New question here. Should I downsize from my 2.8"s to like a 2.5

    Hey everyone,
    I would like to know if I would be better suited to 2.5s or 2.6s as opposed to the 2.8 nobby nics I am currently running on my Kona Big Honzo DL. I have read a couple articles where the journalist did such and was happy with the switch.
    I am 44yrs old, 56 at 150lbs, I dont ride super aggressive but I do like to ramp it up on the flowy stuff and downhills. I am heading to Salida CO for my yearly visit with my childhood friend and we do 3-4 days of riding. Last year I was on a different bike with 2.3s and I am concerned this is too much tire for my needs and that the extra volume and rotating weight will bog me down. I have a hard enough time with climbing at elevation as it is. Has anyone downsized and like the improvement?

    I'm about your age and recently had the opportunity to demo a Honzo. Very nice bike, but I can't really see myself riding a hardtail with smaller tires over anything rough...of course this is only my experience and no one can really tell you what would suit you better (even a journalist trying to sell tires). Have a good trip!

    I don't have any back issues and have always ridden a hardtail, I just don't have superman legs and do like a whippy feel which I feel is a bit less whippy with the 2.8's. Chainreaction has michelin force AM's for 38.99 ea so I wouldn't take a huge hit in the pocketbook. Any opinions on those??

    I've not used them, but the tread pattern looks a lot like a Maxxis Ardent. Some people like this tire design and some don't. Not really a fan, but I know the Ardent rolls decently fast as a rear. I wouldn't put it on the front. That price isn't the best IMO either - quick google search shows ~$35 a couple different places that don't require international shipping.

    You're going to elevation, you're effed no matter what.

    Go have fun with your friend, they won't care how slow you are.

    Zowie, as much as I appreciate your words, I ordered some 2.6 Nobby nics anyways. I'll try and report back with an opinion.
    Thanks Chris

    I'd be interested in hearing if the knobs are taller/larger on the 2.8 vs 2.6.
    Or their older 'regular' sizes, for that matter, if you have a reference.

    injected, your 2.8s would be a lot of fun in Salida! The extra volume will help provide a little cushion and should have great traction, a fair trade off compared to rotational weight. I live in CO and enjoy riding Salida when the opportunity arises. Have an Orbea Loki with 3.0s front and rear, am blown away with the line selections I can take with the plus tires. Whichever way you roll, have a great trip!

    OK heres a quick tire review from a novice midwesterner so take it for what its worth. I ended up going with the new Addix compound 27.5 x 2.6 nobby nics to replace the 27.5 x 2.8s. The tires were the blue line which is the all around use durometer. Not sure about the new Addix compound trademark, and if it is a peer marketing ploy or if the compound really is that different.


    Size- im not sure how these are normally measured but at the widest point the old 2.8s measured pretty spot on at 2.815 and the 2.6s measured 2.585 but grew to 2.7 after a week at 20lbs.


    Someone asked about the knobs and if they were larger. Not Real sure but they definitely look a little different when mounted. Ill post a picture. the 2.8s seemed more roundish and the nobs seemed to protrude more around the side where as the 2.6s seem a little more square this could also be that the 2.8s were being pulled inward more by the 40mm rim, causing a balloon affect. Again Im a rookie at This stuff and just spit balling


    I rode today at 20lbs (tubeless) front and rear (I weigh about 150). Terrain was very mixed with some sand, some loose rock climbing, and a lot of roots. The bike seemed tighter and faster. I wasnt overly concerned about my line choices with rooty sections, bike rolled through the sand well with little wandering. Climbing on loose stuff was a little bit less grabby but still much better than 2.3s. Overall I was very pleased and see no reason to reinstall the 2.8s except for maybe winter. Even though the 2.8s are only .115 wider they just look a lot balloonier (lack of word choice). Let me know if you have any more questions.

    That rounder profile is how a tyre us supposed to look.

    I would suggest only changing the rear to 2.6 and leaving the 2.8 on the front. The only real negative if the larger tyre us the m extra weight and drag but the front adds very little to rolling resistance anyway. The rear however is more likely to fold over in hard cornering and hence the 2.6 would resist this a little more whilst being lighter ans rolling slightly better.
